About our window mastic in Haywood
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Typical jobs include untidy mastic left by window fitters and gaps between the frame and the inside reveal, on window sills, uPVC windows and aluminium frames.
Outdoor sealant needs a dry surface, so window work around Haywood is planned around the weather. Let us know about access to every frame, including any upstairs.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How we quote for window mastic
Every job gets its own quote. This is what makes a difference:
- When we can work, for business premises
- The product the joint needs
- Whether the work is at height
- How many rooms, windows or areas are involved
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- The rough size of the job
- The type of property
- The problem you’ve noticed
- Whether it has been sealed before
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- Faulty window hardware
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.
What we seal
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Patio & French doors
- Composite doors
- Window sills

What happens if it’s left?
The work is quick compared with the damage it prevents: the visit takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What you get with us
- Colour agreed with you before any work starts
- White, clear, grey or another colour, product permitting

Your questions about window mastic in Haywood
Do you work for landlords with property near Breich station?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Is Haywood within the area you cover?
Yes. Haywood is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is the work guaranteed?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work usually takes a few hours for a few frames, or a day or more for a whole house. Outdoor work around Haywood depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Mention any tricky access
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive

Do you need window mastic in Haywood?
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
The most common problems we see are:
- Old mastic that has gone black or come away
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- Gaps where the sill meets the wall
If you let a flat or house near Breich station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Before you book anyone
- What happens if the job turns out different
- Is VAT in the price?
- Which sealant they’ll use, and why
- How the colour is chosen
Keeping the joints in good condition
After the cure time, these simple habits help:
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
- Make sure the drainage slots are not blocked
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
